The loop turns through 180 degrees to re-join the Ely to Peterborough Line in the down (northbound) direction.
Ely West Curve was laid in on 1 October 1890, to allow freight trains from the Midlands and north to run directly onto the King's Lynn and Norwich lines in the down (northbound) direction without reversal thus avoiding Ely station.
